Drawing montains.. (with the same pallete)

I really don't know how to draw montains

I've built a menu. It's pretty simple yet, but I will add some beauty futurely.

Another sort of montains...

Added a cool pause system :)

Got some git problem on game dev?

Waiting is the kind of thing I don't like to do...

Trying to draw montains again...

I'm thinking creating a new game... I've not given much throught to it, even because I was just drawing when I got this idea. So I'm accepting sugestions.

It's a Flappy Bird clone game I'm making :)
